How does a firewall work?
Firewall’s task is to block attack attempts on a network. Firewall monitors network traffic and blocks all connections coming from untrusted recipients. It allows to stop potential attacks even before they have reached the company’s network and devices in it.
Firewall systems can be divided into three types:
Open source firewalls – we implement this type of firewall on Windows and Linux systems.
Commercial firewalls – dedicated network devices. When selecting the equipment, we use mostly Cisco and Fortinet solutions.
Firewalls on network active devices – configuration of firewall systems embedded in network devices.
The implementation of a firewall in a company consists of the following stages:
Purchase of network equipment for the customer.
Configuration of the firewall at the customer’s premises.
Synchronization of the firewall with the rest of the IT infrastructure.
We also offer our clients ongoing administration over network equipment. As part of IT monitoring, we control the correctness of hardware and software operation. We guarantee a quick response and continuous technical support.
